7:10 To teach - The order of things in this verse is very observable; first he endeavours to understand God's law and word, and that not for curiosity or ostentation, but in order to practice: next he consciously practises what he did understand, which made his doctrine much more effectual: and then he earnestly desires and labours to instruct others, that they also might know and do it.
7:1-10 Ezra went from Babylon to Jerusalem, for the good of his country. The king was kind to him; he granted all his requests, whatever Ezra desired to enable him to serve his country. When he went, many went with him; he obtained favour from his king, by the Divine favour. Every creature is that to us, which God makes it to be. We must see the hand of God in the events that befal us, and acknowledge him with thankfulness.
